Looks like your link speed and duplex settings are at 
auto-neg. Your initial post is contrary.

We have a problem here. Was the cable unplugged or interface 
shutdown, perhaps while you were testing?

Suggest you clear these interface counters and try again after 
a few minutes just to eliminate potential hardware/physical 
link issues.

Speed/duplex settings also appear auto.

There was an interface reset there. Was the cable unplugged or 
interface shutdown?

I notice this port is in VLAN 2. Confirm the other switch port 
is also in VLAN 2, and as Kone mentioned earlier, the VLAN 
information is shared between both switches via a trunk.

You also need to define VLAN 2 in your VLAN database on both 
switches for this to work:

Switch# vlan database
Switch(vlan)# vlan 2 name test
Switch(vlan)# exit
APPLY completed.
Exiting....
Switch# 

Just as a test, you could configure another port on the same 
switch (this one, for example) with a VLAN ID of 2 and attach 
the second router to it. If it works, your routers are fine 
and we can turn our attention to the switches.

Cheers,

Mark.
